Assuming that that this is an issue since applications look for this
"generic" volume controls.

The most important information is missing:  Please upload
/proc/asound/card0/codec#* files.

Possibly there is no master volume or PCM control on your chip indeed, but
only volume for each output jack, Front, Surround, CLFE.
